Conventional middleware systems fail to address important issues related to dynamism. Modern computer systems have to deal not only with heterogeneity in the underlying hardware and software platforms but also with highly dynamic environments. Mobile and distributed applications are greatly affected by dynamic changes of the environment characteristics such as security constraints and resource availability. Existing middleware is not prepared to react to these changes. In many cases, application developers know when adaptive changes in communication and security strategies would improve system performance. But often, they are not able to bene t from it because the middleware lacks the mechanisms to support monitoring (to detect when adaptation should take place) and on-the-y recon guration. dynamicTAO is a CORBA-compliant reective ORB that supports dynamic con guration. It maintains an explicit representation of its own internal structure and uses it to carry out runtime customizat...
